About our construction mastic in Hambrook
Refurbishment work needs a slightly different approach from new build. Old beads come out completely, as fresh silicone can’t grip old and the asbestos survey is checked first on older stock. New and existing joints then get the same preparation. If you are dealing with early adhesion failures on new external joints and failed sealant in an existing building being refurbished, we can help, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Hambrook it comes down to the same thing: the right product in a properly prepared joint.
Construction in and around smaller places such as Hambrook is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

When to call us in Hambrook
Most mastic snags on new buildings come from sequencing rather than product. Sealing before decorators, flooring or other trades have finished leaves joints exposed to damage, and the joint has to be redone.
It’s worth sending us details if you spot any of the following:
- Frame perimeters left unsealed or poorly sealed
- Failed sealant in an existing building being refurbished
- Caulk cracking where joints are moving more than expected
- Sealant knocked or painted over by other trades
Historic houses such as Warblington Castle (3.8 miles west of Hambrook) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.
Before you book anyone
- Whether their applicators hold CSCS cards
- Their plan for phasing and protecting the area
- How joint depth will be controlled
- How the existing material will be dealt with
From enquiry to sign-off
Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. Jobs in and around smaller places like Hambrook are normally planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.
- We walk the site or review drawings to understand the package.
- You receive a fixed quote covering scope, products and sequence.
- Paperwork is agreed and applicators are inducted on site.
- Sealing follows the programme as areas are released.
- Any frame gaps or issues outside our scope are flagged to the site team.
- Final snagging is completed and the 12-month guarantee applies.
Before we start on site
- Move anything stored against the joints
- Share your working hours and any access restrictions
- For older buildings, check the asbestos register before work

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. For smaller jobs, photographs and a description will do.

When something else is needed
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Deciding which fire-stopping product a penetration needs
- Joint design decisions that belong to the architect or engineer
- Faulty frames rather than failed sealant
If you’re not sure, just give us a call on 01277 525 020 or send details through our quote form and we will give you a straight answer before you book.
Surfaces we seal
- Internal decorators’ caulk
- Brick and block movement joints
- Floor and skirting junctions
- Cladding and panel joints
- Sanitary and kitchen joints
- Window and door perimeters
Common questions from Hambrook clients
Can you work around term dates at a campus such as University of Chichester?
Yes. We plan campus work around teaching, exams and residence turnarounds. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Is Hambrook Business Park, near Hambrook, within your area?
Yes. Estates, retail parks and business parks around Hambrook, Hambrook Business Park among them, are all within reach. Photos and a short description are enough for a first look.
What happens if old sealant might contain asbestos?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.
Do you install fire-rated sealant as part of a package?
Fire-rated sealant can be included where it’s specified, installed to the product’s tested detail. The design and sign-off belong to the designer, fire engineer or building control.
Does weather affect external mastic work?
Outside, the joint has to be dry and the temperature within the product’s limits. Damp, frost or condensation on frames can stop work so we typically switch to internal work when that happens.
What joints do you seal on a new build?
Inside and out: frame perimeters, movement joints, caulk where called for, sanitary and kitchens.
Contractors’ notes for Hambrook
Hambrook lies within about 2 miles of the sea. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. At about 56 miles from central London, Hambrook is within reach of the capital. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and main contractors there need mastic that keeps to the programme.
When a school such as Chidham Parochial Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. On a campus such as University of Chichester, which lies east of Hambrook, new teaching buildings and residences are normally built and refurbished around the academic year.
Hambrook is about 5 miles west of Chichester, in West Sussex. Across the PO18 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Hambrook is one of 373 places we cover in West Sussex. Portsmouth is covered too, some 9 miles away.

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Hambrook can form part of a wider programme across West Sussex.
Looking after the joints
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Use the product the specification names
- Protect sealed areas from following trades
- Keep scrapers and abrasive pads off new beads
- Release areas for mastic once other trades have finished in them
At handover, keep the product details with the O&M information. Future maintenance is easier when the products are known, and tells you what to reseal with. We can confirm the handover information you need when we quote.
Snag items left to the last week put handover at risk. Clearing snags area by area spreads the work out.
Leave it or put it right?
On a refurbishment, there’s a choice between resealing existing frames and replacing them. Sound frames often need only a new perimeter seal and that’s a far smaller job. If the frame is life-expired, we’ll tell you. Older rural buildings around Hambrook move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.
